Hello. I'm trying to set up a VLAN on a rutx09 router.

What I want to do is to configure that router's WAN port (it is bridged to eth0 and eth1 to use as a LAN port) will be used for the other wifi router thats only connecting other computers to the internet. I want that the traffic which goes through the WAN(LAN port) will be totally isolated from the other LAN ports. So I want to use this wan port and rutx09 4G modem as a gateway connecting wifi router to the internet.

I have no clue what this TAG or UNTAGGED totally means. Need help how to configure WAN port as a totally isolated network.

Thanks you for the replies!

Hello,

There is a guide on how to set WAN port as LAN: https://wiki.teltonika-networks.com/view/Setting_up_WAN_as_LAN

And there is a full explanation on VLAN' (by default VLAN's are isolated from each other): https://wiki.teltonika-networks.com/view/RUTX09_VLAN

Hello

Thank you for your response. I successfully managed to config WAN port as a LAN port. However I'm totally out of ideas how to configure this WAN port as an isolated network from LAN1,LAN2,LAN3. I tried creating a new VLAN with ID 103. There I put WAN Tagged, all other Off. Then I did a new connection under Interfaces gave a different Static address for this VLAN. Then activated DHCP server. Then under Physical interfaces i tried eth0.103. Then clicked enable. The devices in this WAN port can connect to internet and also communicate with other devices on the network. When under VLAN I change WAN from Tagged to Untagged, it is not possible to connect to internet. I have read the Tagged and Untagged VLAN chapter under Rutx09 like a over 10 times. Tried different setting but I'm not able to isolate the networks from each other.

I would appreciate if someone could upload somekind example in how to configure the VLAN etc.
